I think we can count ourselves lucky we haven't had any especially when you look at the damage to the Swr unit.

It doesn't strike me as a hugely difficult IT problem (if built as an added failsafe on top), but the question would be more whether UK track circuit block signalling is built that way or not?
Can I just say that I think it's sickening that there's some railway/emergency services worker getting their rocks off at sharing images from the scene.
The BBC have got hold of 2 pictures from inside the tunnel

Or evacuated passengers? There’s allegedly a video on tiktok inside a carriage according to a Facebook comment I’ve just scrolled past!

They just broadcast a video of one of the trains outside the tunnel. The units headlights switching on and offThe BBC have got hold of 2 pictures from inside the tunnel

Agreed. Best not to let this thread be a repeat of the Carmont one in this respect.
It could just be a passenger that was on the train, 99% of them will have a camera on their phone.
There's always going to be something on TikTok! People involved in any incident these days will want to let as many people as they can know, and hope it will go viral. Sad but true.

It appears so, I've seen an image that appears to be from a video of the inside of one of the units, which has a Tik Tok watermark. I won't be sharing it for obvious reasons.

As a point of order, two passenger trains were involved, which by definition would have been carrying passengers. Nowadays pretty much everyone has a camera phone and the ability to share images instantly.
It could be I suppose, but that PlaneTrainHub chap on Twitter has said he got them from a railway source.

Those will be the headlights switched to hazzard to warn other trains
Probably got hazard mode switched on, which flashes them similar to the indicators on a car.

Hazard lights are a common feature on newer lighting units. Any train coming the other way should apply the emergency brake and contact the signaller immediately.

Indeed. That's what WhatsApp is for. Far more information on that than official sources

I'm a bit confused, has that GWR unit split in half.
it wouldnt be a rear cab the train is travelling on the left hand rail which is the rails it would be driving on in the direction. Just a thought.

Thats what I was thinking, the image show in the tunnel makes no sense

The unit in the photo in post #134 could be 1F27?

Signals should have batteries which would keep them lit if mains power is lost and the signal protecting the junction certainly did in 1980. If there are any problems, then they should go to red. I am not going to speculate further on something that is very odd.

Sorry this is speculation but
Moderator note: This is not the case; it is a fixed diamond
Yes I was wondering that. Sorry for the speculation but I was wondering if the diamond crossing is a switched diamond then its possible that the second train was diverted onto the other line.

It is possible and newer systems than that at Salisbury (the control system rather than the interlocking as I understand it) detect a track circuit occupying or clearing out of sequence. I don't know whether it puts signals back to danger though.
I'm assuming the driver should treat it as a red if the signal has lost power completely and is not lighting.
do they have any reflective stuff on them to help a driver see a unit signal. maybe the number plate?
